For a man who spent nearly four decades of his seventy-six years under the restrictive eye of the US correctional system, few have ever lived life as fully or touched as many as Rubin “Hurricane” Carter. The world-class boxer turned wrongfully accused prisoner, turned advocate for the rights of the unjustly incarcerated, has succumbed to cancer, but his memory and work will endure as long as there are people outside and inside the prisons of the world, fighting for justice.

Few prisoners have had their story both enshrined and shouted from the highest hills of popular culture like Rubin Carter. After his own infamous homicide conviction, Carter’s case inspired an international human rights movement. There were rallies, marches and even all-star musical concerts in his name. He was the subject of a Bob Dylan Top 40 hit, the frenzied fiddle anthem Hurricane. Carter also wrote, while behind bars, the bestselling book The Sixteenth Round: From Number 1 Contender to Number 45472. Finally after his release, he was the subject of the Oscar-nominated Denzel Washington film The Hurricane.

Yet despite his release as well as a Hollywood canonization, Rubin Carter never rested. After decades behind bars, no one would have blinked if he had coasted on his celebrity for the remainder of his days. Instead, Mr. Carter started a nonprofit organization in his adopted home of Toronto in 2004 called Innocence International, aimed at shedding light on the cases of the wrongly convicted. Rubin Carter believed that the only thing exceptional about his conviction was the fact that people were aware and outraged that it had happened. In a country with the highest prison rate on the planet, where quality legal representation is more privilege than right, Rubin Carter knew that he had left an untold number behind, forgotten in a catastrophic system as inert as it is cruel and unusual. He had seen the racism, he had lived among the poor and mentally ill behind bars, and he was determined to be their advocate. Carter wrote as he lay dying that he “lived in hell for the first 49 years, and have been in heaven for the past 28 years.” For him, heaven was doing this kind of work.

I had many an interaction with Rubin Carter, never revolving around boxing or his near-miss in 1964 to win the middleweight championship. Our shared work existed in the context of campaigns to see those who may be innocent, have their day in court. Rubin Carter never refused any of my requests, no matter how obscure the case, to get him to lend his name to a campaign. Like Denzel Washington said when he took Rubin Carter on stage with him when accepting the Golden Globe for best actor for The Hurricane, “He’s all love.”

Sure enough, during the last days of his life and in terrible pain, Rubin Carter was attempting to bring light to yet another prisoner he believed was being denied justice in the massive shadows that flood this country’s criminal justice system. On February 21, 2014, Carter published “Hurricane Carter’s Dying Wish,” in the New York Daily News. It detailed the case of David McCallum, who has been jailed for murder for almost thirty years, convicted at the age of 16. As Carter wrote, “McCallum was incarcerated two weeks after I was released, reborn into the miracle of this world. Now I’m looking death straight in the eye; he’s got me on the ropes, but I won’t back down…. My aim in helping this fine man is to pay it forward, to give the help that I received as a wrongly convicted man to another who needs such help now.”

The best possible tribute to Rubin Carter would not be to listen to some Bob Dylan or read a few obits. It would be to contact new Brooklyn District Attorney Ken Thompson – his “action line” phone number is 718-250-2340 — and ask him to fulfill Hurricane’s request to reopen the case of David McCallum. After all, this was the dying wish of the Hurricane.
